Special Anti-interference Material Non-magnetic Tungsten Carbide Core Ring
μ-grade non-magnetic tungsten carbide core ring with magnetic permeability of <1.002
When precision measurement encounters magnetic field interference, this non-magnetic core ring provides the ideal solution. Precision-manufactured using nickel-bonded tungsten carbide (WC-Ni) with a special demagnetization process, it eliminates magnetic interference issues associated with traditional tungsten steel parts. Ensures zero magnetic interference, high precision, and long-life stable operation in magnetic field-sensitive environments.
Non-Magnetic Principle: A Breakthrough in Materials Science
Non-Magnetic Mechanism:
Nickel-based binder phase replaces traditional cobalt phase
Magnetic permeability controlled to <1.002
Residual magnetization <0.05 mT
Matrix material: 90% WC + 10% Ni, non-magnetic formula
Hardness: 92 HRA (Vickers hardness 1800 HV)
Density: 14.8-15.1 g/cm³
Resistivity: 0.8-1.2 μΩ*m
